Ogawa Kazumasa (1860-1929) was a Meiji era photographer, printer, and publisher, who was a pioneer in the field of photography and photomechanical printing.
Following a post on reddit (I know never trust what you read on reddit) this lora was a kind of experiment to see how well flux would train without any caption using only 10 images that I found under free license. Honestly I'm surprised, but it does add an interesting old printed art look.
Use the ogaka trigger if you like.
